Patented May 7, 1946 UNITED STATES PATENT OFFICE 1 Claim.

This invention relates to new and useful improvements in gun sights and more particularly to what may be known as a peep sight.

One important object of the invention is to provide a rear sight structure for rifles which will permit a quicker concentration of the sightsof a riiie on an objective due to the more rearward location of the rear sight.

Another important object of the invention is to provide a rear sight for rines, adjustably located on the stock of the gun so that the riileman can more readily iind the rear sight with his eye and line up on an objective, than in instances where the rear sight is located on the breech or barrel portion of the gun.

Another important object of the invention is to provide an eye cup or light shade for the rear sight against which the hunter can rest the portion of his face surrounding his aiming eye for the purpose of excluding light and more definitely concentrating on the fore-sight and objective.

Other objects and advantages of the invention will become apparent to the reader of the following description.

In the drawings:

Figure 1 represents a side elevational View of a gun equipped with the present invention.

Figure 2 is a top plan view of the structure shown in Figure l.

Figure 3 is a section on the line 3-3 of Figure l.

Figure 4 is a fragmentary enlarged side elevational view of the stock portion of a gun showing the cover plate removed.

Figure 5 is a section on the line 5--5 of Figure 1.

Figure 6 is a fragmentary vertical sectional view through the rear sight.

Figure 7 is a section on the line 1-1 of Figure 3.

Figure 8 is a side elevational view of the adjustable post.

Referring tc the drawings wherein like numerals designate like parts, a block or protuberance 6 is provided on a side of the particular gun y stock 5. This block 6 serves as a support for the rear gun sight generally referred to by numeral 1.

Numeral 8 generally refers to a conventional rifle having a barrel 9, a front sight I0, the rear sight l, which is the present invention, and an intermediate leaf-type sight II mounted cn the barrel 9. The leaf-type sight I I is not used when the rear sight 1 is to be used, but is swung downwardly on the barrel 9 out of the range of the sights I and I0.

The block 6 is formed with a substantially square pocket I 3 in the lower pori-,ion thereof and this is closed by a removable plate I4.

Situated in the pocket I3 is a plurality of vertically disposed compression springs I5 which bear at their upper ends against a follower block I6 which, in turn, bears against the lower end of an elongated bifurcated riser I'I which is pivotally secured to the block 6 by a suitable member I8.

The upstanding leg portions I9, I9 of the riser I'I are spaced apart to accommodate a vertically movable post 29 having serrations 2| along one side thereof and with which the toothed member 5 22 of a spring 23 secured to a band 24 is selectively engageable, this band being secured by screws or the like 25 to the upper end of the riser Il.

Suitable graduations for elevation may be pro- 10 vided on the post 20 and these are denoted by a reference character 26. A small knob 2'I is provided on the tooth 22 for permitting disengagement of the tooth with respect to the teeth of the post 20. f l5 Numeral 28 denotes an eye cup or rubber guard adapted to snugly iit the face of the gunner around the aiming eye. The upper portion of the post is reduced and formed as at 29, the eye cup fitting against one side of this, while against 20 the other side is disposed a clamp plate 30. There -is also a second clamp plate 3| and these clamp plates at their adjacent sides are formed with depressions to receive an apertured eye piece plate 32 having a small sight aperture or peep hole 33 therein. The clamp plates 30, 3|, the portion 29 of the post 20 and the bore portion of the cup or guard 28 are provided with larger openings 34. The clamp plates 30, 3| are secured together by screws or the like 35 and, of course, the cup 28 is secured to the post 20 in any desirable manner. The purpose of the springs I5 is to absorb or compensate for the recoil of the gun when firing. The springs are for flexibility to the rear sight structure.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

Having described the invention, what is claimed as new is:

A gun peep-sight comprising an eye piece plate, a cup-shaped eye guard, a post supporting the eye guard and having a flat bottom portion and a portion projecting into said eye guard, a pair of clamp plates at the top end of the post, said eye guard, top end of the post and clamp plates being formed with registering openings, said eye piece plate being interposed between the clamp plates v having a relatively small sight opening therein registering with the other openings, a, yieldable support for said post, consisting of a block adapted for fixing on the gun stock, and provided with a pocket, a table in said pocket in contact with the flat bottom of said post, said table resting on compression springs in the pocket beneath said table in order to hold said post upright, a pivot pin for said post on said block above said table for oscil lation in a vertical plane of the gun bore.
